Edible mushroom fertilizer what to want.

Edible mushroom topdressing has "four to", farmers all need.

In the late stage of mushroom production, in order to enhance the aftereffect of mushroom production, mushroom farmers often add nutrient solution for topdressing. However, only by using the correct method to add nutrient solution can the expected purpose be achieved, otherwise it will be counterproductive and bring losses to producers.

There are usually three ways to add nutrient solution: spraying, soaking and irrigation.

The suitable time of spraying nutrient solution was when the fruiting body appeared in large quantity. When spraying, pay attention to the spray nozzle not facing the fruiting body, and pay attention to the "four no-spraying": young mushroom buds do not spray, so as not to "swell and die"; just picked mushrooms or mushroom residues do not spray, so as not to cause bacterial diseases; air humidity is too high, do not spray; mushroom shed (room) serious diseases and insect pests do not spray.

Soaking method should be used for bag cultivation of edible fungi. After harvesting 1-2 crops of mushrooms, if the cultivation bag is in a serious water shortage state, it can be soaked in the prepared nutrient solution until it recovers or approaches the original weight. The nutrient solution is added by soaking method, which only needs to immerse the bacteria bag in the nutrient solution and then press heavy objects, but the soaking time should not be too long. If the bacteria bag loses too much water, it can be soaked several times.

Point irrigation method is mainly used in the fungus bed, when the fungus bed more mushrooms, water and nutrient consumption is too large can be used this method. The concrete method is: drilling the bacterial bed according to the hole spacing of 10 cm, flooding the prepared nutrient solution into the bacterial bed, and covering the soil after adding the nutrient solution.

Concentration should be appropriate: nutrient solution concentration is too high, not only difficult to absorb hyphae, but also hinder or even damage hyphae; concentration is too low, the effect is not obvious, can not achieve the purpose of high yield. The concentration of nutrient solution depends on the moisture content of the culture medium. If the water content of the culture medium is high, the concentration of nutrient solution should be increased, the water consumption should be reduced, and the ventilation amount should be increased after adding nutrient solution. On the contrary, the concentration of nutrient solution should be reduced and water consumption increased.

Nutrient solution nutrients should be comprehensive: several nutrient solutions should be used alternately frequently, so that the nutrients obtained by the sub-entity are comprehensive and reasonable. If hormones are used to stimulate the growth of edible fungi, they should be used after supplementing nutrient solution.

Pay attention to the change of environment: when the temperature reaches above 20℃, it is difficult for hyphae to form high-quality fruiting bodies (except for high-temperature edible fungi varieties), and nutrient solution can not be added. If the culture medium has been contaminated by miscellaneous bacteria, be sure to remove the miscellaneous bacteria before adding nutrient solution. In order to prevent contamination by miscellaneous bacteria, a certain amount of bacteriostatic agents can also be added to the nutrient solution to prevent the breeding and spread of miscellaneous bacteria.

There are usually three ways to add nutrient solution: spraying, soaking and irrigation. The suitable time of spraying nutrient solution was when the fruiting body appeared in large quantity. When spraying, pay attention to the nozzle not to face the fruit body, but also pay attention to the "four do not spray":1. Young mushroom buds do not spray, so as not to "swell".2. Just picked mushrooms or mushroom residues do not spray, so as not to cause bacterial diseases. 3. Do not spray when the air humidity is too high. 4. Mushroom shed (room) when serious diseases and insect pests do not spray.

Soaking method is mainly used for bag cultivation of edible fungi. After harvesting 1 ~2 crops of mushrooms, if the cultivation bag is in a serious water shortage state, it can be soaked in the prepared nutrient solution until it recovers or approaches the original weight.

Point irrigation method is mainly used in the fungus bed, when the fungus bed more mushrooms, water and nutrient consumption is too large can be used this method. The concrete method is: drilling the bacterial bed according to the hole spacing of 10 cm, flooding the prepared nutrient solution into the bacterial bed, and covering the soil after adding the nutrient solution.

When the concentration of nutrient solution is too high, it is not only difficult for hyphae to absorb, but also hinders or even damages hyphae. When the concentration is too low, the goal of high yield cannot be achieved. If the water content of the culture medium is high, the concentration should be increased, and the ventilation amount should be increased after adding nutrient solution. On the contrary, the concentration of nutrient solution should be reduced and water consumption increased. Commonly used nutrient solution concentration is: urea 0.3%~0.5% potassium dihydrogen phosphate 0.2% and so on, we must grasp the principle of "less and more".
